The Clean Air Act, as amended in 1977, requires periodic review and revision of all national ambient air quality standards (NAAQS) to insure that they are based on the latest scientific information. This article presents an overview of how EPA currently reviews and establishes NAAQS. The role of scientific information and expertise in the process is illustrated by a review of several key issues faced in the development of the proposed revisions to the carbon monoxide NAAQS. Finally, a risk analysis framework being developed within EPA's Office of Air Quality Planning and Standards for possible future use in NAAQS reviews is described. The principal objective of the risk analysis framework is to provide more formal treatment of uncertainties in the scientific data base.
1977年修订的《清洁空气法》要求定期审查和修订所有国家环境空气质量标准（NAAQS），以确保这些标准基于最新的科学信息。本文概述了美国环境保护局（EPA）目前审查和制定国家环境空气质量标准的方式。通过对一氧化碳国家环境空气质量标准拟议修订案制定过程中面临的几个关键问题的审查，说明了科学信息和专业知识在这一过程中的作用。最后，介绍了EPA空气质量规划与标准办公室正在制定的一个风险分析框架，该框架可能在未来用于国家环境空气质量标准审查。风险分析框架的主要目标是更正式地处理科学数据库中的不确定性。
